Lemme splain something to you Lucy. My 98 24V was custom programmed by Mark Chapple (Retired Cummins performance engineer) of TST Products as his first upgrade to the new electronics engines. Of course he was shut down on that avenue as Cummins said their programming was proprietary and owned by them alone. So back to the drawing board he comes out later with a power added box (forget the name). So I go to his shop and get it installed and ask what about the previous program. He says I am lucky, I get power on top of power. How much? He estimates 900LBS torque (he knows his stuff). Says I will fry tranny very quickly if I turn it up too much. Boy was he spot on. Tranny died very quickly and I had one built (plug for Tim Moy Transmissions, Lutz FL) that could handle the power.
I say all that to say this. My 98 would twist the frame a little when hard on the pedal. You could tell when letting off and it would jerk to the right (or left, I can't remember) I had a deleted mild tune 08 and now have a 14 with like a supposed 800LBS torque. Neither truck is even close to the 98. These are all brochure numbers and have nothing to do with real world towing. I firmly believe my 97 12V could tow as well as my 14.
Don't get me wrong, I love my Cummins and my new truck. Would rather have a low RPM high torque bus engine though. Next time your on a bus listen to the engine and feel how the bus accelerates. Problem with an engine tuned like that is the HP numbers would kill sales.
Ready to take my lumps now. Request all flaming to be around a campfire with red cups in hand!
